mod_vcard_legacy: Create nodes with open access (fixes #1221) Less drastic change from mod_vcard where everything is always public. This allows users to configure nodes without needing to for the old behaviour. Thanks to 038446c50630 users may still override this. Due to #1222 this may still not apply if the node has already been created by an automatic subscription

-- Unknown platform stub
module:set_global();

-- TODO Do things that make sense if we don't know about the platform
